What is the best Reel To Reel machine ever built?


Everyone who has listened to master tapes or dubs knows about the well balanced sound they provide. But it is also important to have a fine tape recorder or playing machine to enjoy the tapes' qualities in a good system.
Maybe my question was raised once before but the relevance of the topic is now greater as the tapes are back to more and more audiophile friends, especially those who are owning excellent phono chains.

I have seen many big & professional machines being recently offered and sold on e-bay, Audiogon and other platforms and I am discussing within a small group which machine is really the "holy grail" among the R2Rs. So why not here. I am interested in findings.

Mike,
your A820 looks like it is in a very good condition. It is of course the crown of all modern Studer machines with five motors and its build quality is from another world. It is also a very rare type you have. You are very priviliged to work with such a machine. I was told the weak point may be the computerized design. new parts a not easy to get but I do think this counts for all Studers exept of the A810.
Oh yes the Nagras. What about the Sonys and MCIs?

Alright, MIKE!!

First, there was the tribute to vinyl...
and now...
the R2R arsenal :-)

Of course, there is Ki's pantheon to analog reel tape!

I have a Studer A-820 ;-)

Eckart -- how're you doing?
I use Sony TC 765 for all my replay....not the super machine, but very good sound and build to last.......
Dear all,
thanks for contributing so far. I know about the Studer machines but there are so many other nice machines out there. I recently saw a vintage Sony prototype on ebay in very good condition, only a little overprized.

Sam, oh yes you are a lucky owner of a A820. May I ask you and Mike if are using the A820 at 30 ips?

Besides of the A820 which machine really has "best of all time status" or which one would you recommend going for?

Even though I myself won't be pursuing R2R (not enough easily available material I'm interested in to play), one thing I would be curious about is what these R2R worthies think of the vinyl vs. tape comparison. Too often, it seems to me, the magic word "analog" is bandied about almost exclusively in relation to vinyl, to which it is not a synonym. An occasional reminder of the difference could be healthy for the perspective, I believe.
